Only plant cells

Answer 1

• Chloroplasts are found in plant cells
• They are filled with chlorophyll which makes the leaves green.
• They absorb sunlight so the plant can carry out the process of photosynthesis.

Answer 3

• A jelly like substance
• This is where chemical reactions take place in order to keep the cell alive.
• These reactions are controlled by the enzymes in the cell.

Question 4

What is the cell wall?

Only in plant cells

Answer 4

• Covers the cell membrane

* Made of tough cellulose giving the cell strength and support.

Question 5

What is the nucleus?

Answer 5

• Contains all of the genetic material to produce new cells

* Controls the activity of the cell including the chemical processes.

Question 6

What is the vacuole?

Answer 6

• Filled with a weak solution called cell sap containing salt and sugar.
• It also supports the cell

Question 7

What is the cell membrane?

Answer 7

• Thin, skin like layer inside of the cell wall

* It gives the cell its shape and controls what enters and leaves the cell.

Question 8
